4. • Omega lap former is winding the lap/batt by belt drive and
tensioning system.
• It is fully automated.
• In omega lap former in winding process are two winding
rollers ,four calendaring rollers .
• The winding belt width is similar to the lap .
• the maximum lap winding start of the lap are 120 to 140
m/min and have to be reduces as low 80 m/min as lap
diameter increase.
.

5. • The ranging angle from 180 to 270 from start to full lap.
• The surrounds of the lap to form a circumferential pressure
area ( Ω omega-shaped ).
• The slivers are the input of the omega lap former and
output is lap.
• E 35 omega lap production up to 520 kg/h.
• it’s low energy consuming result to the use of energy
optimized electronic and simple mechanical drive elements
and high output.

6. First the empty tube is inserted; two winding
rollers/discs closed pneumatically to secure the tube in exact
position.

7. Belt unit is closed and tensioned the material is fixed pneumatically in
position of tube, the winding process start.

8. The lap/batt wound on the tube at constant speed until full lap
diameter is reached.

9. The machine is stopped, the belt unit opened, the full lap
ejected toward front
